• Design, build, and maintain an Android observability SDK used by external developers in production at scale • Work on crash capture (JVM and NDK), ANR detection, performance tracing, and session orchestration • Develop and maintain native (C/C++) components including signal handling and JNI bridges • Evolve the SDK’s OpenTelemetry integration, spans, traces, and distributed tracing via W3C Traceparent • Build reliable mechanisms for offline storage, batching, retries, and telemetry delivery • Optimize for minimal SDK overhead: startup time, memory footprint, thread usage, and binary size • Own API surface design, binary compatibility, and versioning for a public SDK • Debug complex issues across devices, OS versions, OEMs, and customer environments • Contribute to architectural decisions across a modular SDK codebase • Establish best practices for testing, release safety, and code quality • Partner with cross-platform SDK teams (React Native, Flutter, Unity) to maintain internal bridge interfaces and ensure native changes do not break downstream consumers
